This commit adds proper support for import assertions and JSON modules.
Implementation of "core/modules.rs" was changed to account for multiple possible
module types, instead of always assuming that the code is an "ES module". In
effect "ModuleMap" now has knowledge about each modules' type (stored via
"ModuleType" enum). Module loading pipeline now stores information about
expected module type for each request and validates that expected type matches
discovered module type based on file's "MediaType".
Relevant tests were added to "core/modules.rs" and integration tests,
additionally multiple WPT tests were enabled.
There are still some rough edges in the implementation and not all WPT were
enabled, due to:
a) unclear BOM handling in source code by "FileFetcher"
b) design limitation of Deno's "FileFetcher" that doesn't download the same
module multiple times in a single run

Fixes "op_set_exit_code" by sharing a single "Arc" between
all workers (via "op state") instead of having a "global" value stored in
"deno_runtime" crate. As a consequence setting an exit code is always
scoped to a tree of workers, instead of being overridable if there are
multiple worker tree (like in "deno test --jobs" subcommand).
Refactored "cli/main.rs" functions to return "Result<i32, AnyError>" instead
of "Result<(), AnyError>" so they can return exit code.
This change also makes the timers implementation closer to the spec, and
sets up the stage to implement AbortSignal.timeout() (whatwg/dom#1032).
Fixes #8965
Fixes #10974
Fixes #11398
Although not easy to replicate in the wild, the `deno test` op sanitizer
can fail when there are intervals that started before a test runs, since
the op sanitizer can end up running in the time between the timer op for
an interval's run resolves and the op for the next run starts.
This change fixes that by adding a new macrotask callback that will run
after the timer macrotask queue has drained. This ensures that there is
a timer op if there are any timers which are unresolved by the time the
op sanitizer runs.
Due to a bug in V8, terminating an isolate while a module with top-level
await is being evaluated would crash the process. This change makes it
so calling `worker.terminate()` will signal the worker to terminate at
the next iteration of the event loop, and it schedules a proper
termination of the worker's isolate after 2 seconds.

Set the exit code to use if none is provided to Deno.exit(), or when
Deno exits naturally.
Needed for process.exitCode Node compat. Paves the way for #12888.
Reduce the number of iterations from 1,024 to 128.
On my big bruiser of a desktop machine it already takes up close to a
minute to complete when nothing else is running so no way it's going to
finish in the allotted time on the CI.
The fact that the test used to pass may be indicative of a performance
regression somewhere but it's not clear to me when or where that would
have been introduced.
Fixes #12887.
This commit introduces "ProcState::maybe_resolver" field, which
stores a single instance of resolver for the whole lifetime of the
process, instead of creating these resolvers for each creation
of module graph. As a result, this resolver can be used in fallback
case where graph is not constructed (REPL, loading modules using
"require") unifying resolution logic.
This commit changes formatting of elapsed time in test
runner output.
Instead of "XXXms", reporter outputs one of:
- "XXXms" for <1000ms
- "XXs" for <60s
- "XXXmYYs" for >=60s
This commit integrates import map and "classic" resolutions in
the "--compat" mode when using ES modules; in effect
"http:", "https:" and "blob:" imports now work in compat mode.
The algorithm works as follows:
1. If there's an import map, try to resolve using it and if succeeded
return the specifier
2. Try to resolve using "Node ESM resolution", and if succeeded return
the specifier
3. Fall back to regular ESM resolution
Closes #11826
**BREAKING CHANGE** this behaviour was disable when introduced in Deno 1.14/TypeScript 4.4. It will highlight code that unsafely handles variables that are caught, and will cause type errors in unsafe code.
Closes #11882
BREAKING CHANGE: Previously when `--location` was set, the unique storage key was derived from the the URL of the location instead of just the origin. This change correctly uses just the origin. This may cause previously persisted storage to change its key and data to not be available with the same location as before.
This commit adds CJS and ESM Node resolvers to the "--compat" mode.
The functionality is spread across "cli/compat" module and Node compatibility
layer in "deno_std/node"; this stems from the fact that ES module resolution
can only be implemented in Rust as it needs to directly integrated with
"deno_core"; however "deno_std/node" already provided CJS module resolution.
Currently this resolution is only active when running a files using
"deno run --compat --unstable <filename>", and is not available in other
subcommands, which will be changed in follow up commits.
Returns empty values in case of errors, source lines are non-essential anyway. These errors can happen e.g. when source files change at runtime. A warning is also printed to help us track when it happens in unexpected cases besides this.
